Comparing two types of transcatheter aortic valves for patients with valve deterioration

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The VIVALL-2 study is a randomized trial designed to compare the effectiveness of the self-expandable Allegra valve and the balloon-expandable Edwards valve in patients with severely degenerated biological aortic surgical valves. A total of 104 patients will be enrolled and randomly assigned to receive one of the two valve systems during a valve-in-valve procedure. The primary outcome will be assessed through trans-thoracic echocardiography to measure the trans-aortic mean gradient at 30 days post-procedure. Secondary outcomes will include the rate of moderate or severe prosthesis mismatch at the same time point.

Why it matters

Who can join: the full rules

Inclusion Criteria:

Patients meeting ALL the following criteria will be included:

* Patients aged ≥ 18 years.
* Severe haemodynamical valve deterioration of a biological aortic valve implanted surgically, including severe valve stenosis (effective aortic valve area \< 1.0 cm2) and/or severe valve regurgitation.
* The patient has cardiac symptoms and/or deterioration of left ventricular ejection fraction attributable to the aortic valve disease.
* Heart team decision of VIV procedure.
* Patient is willing to return at 30 days for TTE and to be clinically contacted at 1 year.

Exclusion Criteria:

Patients meeting, at least, 1 of the following criteria will be excluded:

* Patients who openly express their refusal to participate in the study.
* Female patients in gestational age.
* Presence or suspicious of biological aortic valve thrombosis.
* Known hypersensitivity or contraindication to antithrombotic therapy (or inability to be anticoagulated during the procedure), nitinol, or sensitivity to contrast media which cannot be adequately pre-medicated.
* Ongoing sepsis and/or suspicious or diagnosis of endocarditis.
* Patients whose life expectancy is \< 1 year due to non-cardiac comorbid conditions.
* Medical, social, or psychological conditions that preclude the subject from appropriate consent or adherence to the protocol required follow-up exams.
* True inner diameter of the prosthetic valve \> 27 mm.
* Transfemoral access inadequate to accommodate an 18F sheath.
* Patients included in other clinical trials (excluding registries).
